24 Claims. This invention relates to detention window as- `semblies and in `more particular to windows `A`n `olliject of this invention is to provide a win wherein detention means are incorporated into `the window assembly.

This application is a` continuation-:impart of my copending` application Serial No. 82,847 filed June 1, 1936, for Window assembly, wherein the claims relate to the interlocking arrangement of 4the bars, the key bars, etcetera, without-refer-V l "Other objects and advantages `reside inthe construction of parts, the `combination thereof andthe mode of operation, as will become more apparent from the following description.`

In some types of duo-functional window assemblies where "thetransversely arranged bars function both as, detention bars and as muntin bars,' diiculties have been encountered in securing the necessary cheapness of construction without sacricing the appearance and eiciency of the window. .This is further complicated when providing adequate protection across the more lvulnerable area, that is, across the Ventilating area, fi'hishas.V been accomplished in part by (Cl. 18S-64) `providing interlocking detention bars, which have been shown and described in my application Serial No. 82,847. T'his has been further accomplished by providing a closure unit for the ventilating area attachable in the eld to the main structure and providing capping members of tool resistant material `for the muntin bars.

` In the present modification the vertical muntin bars Ill constitute eye bars having openings or eyes l2 longitudinally disposed with respectto the web of -.the vertical bars l0, as more fully disclosed andxclaimed in the above referred to copending application. These vertical bars lll `may be T-shaped in cross sectional area, or any other suitable shape. As the side bars I4 are emj bedded in the masonry, these bars need not necessarily be the same shape as the vertical bars I0; but may have oppositely disposed flanges I6 and I8, the former receiving `the glazing 20 and the latterembedded in the masonry. The bars 14 may also be provided with eyes or openings `similar to and aligned with the openings in the Webs of the vertical bars lll.

needle bars and may be T-shaped in cross sectional area, the stemof the T being provided with a downwardly projecting ange 24 at one side thereof, to give rigidity to the bar to provide protection to the key bars, thereby protecting the bar against erosion caused by rain, snow or moisn ture from the air. The needle bars 22 are passed `32 may be nestled in the corner formed by the -web and the downwardly projecting fiange 2li.`

When the key bars 32 are associated with detention windows, these key bars` may be made of tool resistant material and thus interfere with the easy severance of the muntin bars extending in parallel relation thereto. `By -this structure the higher priced material is confined to the key bar, cheaper material `being used in the eye bars, thereby eiecting ,economy and cheapness. `The vertical muntin bars YI l) vare not protected against sawing or severance by the key bars 32.

.For institutions used in conning or excluding hard-boiled criminals or others, additional protection may be necessary. Without additional protection it is possible for the inmates to sever the vertical muntin bars IU, the severed ends giving the inmates a good leverage to twist, bend or deflect the horizontal detention bars even though these are not severed.

If tool resistant bars were extended in parallel relation to the vertical muntin bars and positioned in a manner similar to the horizontal key bars 32,. such bars would interfere with the glazing of theY glazed spaces of the window. In the modification disclosed in Fig. 4, bars 40 of tool resistant material extend in parallel relation and in close contact with the muntin bars I8 extending across the Ventilating area, the tool resistant bars 40 terminating at the boundary of the Ventilating area. The detention bars 40 prevent the easy cutting of the portions of the muntin bars I0 functioning asfdetention'barsfex'- tending across the Ventilating area, which is the more vulnerable portion of the window.

The detention bars 4U protect the more vulnerable portion of the window. However, Vthese do not take care of the portions of the muntin bars extending across the glazed areas of the window. The portions of the muntin bars vl() extending across the glazed area are protected by capping members 5U overlying the flanges of the muntin bars Il; Bars of other shapes can be used equally as well in many types of structures. These capping members 50 preventthe severance of the muntin bars l0; but do not interfere with the glazing of the fixed spaces', as the capping members 50 are placed on the inside of the glazing along the flanges. The capping members 50, which are preferably made from tool resistantA material, are very effective in preventing the inmates from severlng the muntin bars above or below or to either side of the Ventilating area. The capping members 5 0 could extend uninterruptedly from the top to the bottom ofthe window across the ventilating area, providing the closure frame is provided with clearance for these capping members 50. This, however, will result in a thicker or more massive structure, as the vclosure for the Ventilating area would probably project further outwardly away from the main structure than the closure in akwindow where the capping members do not extend across the Ventilating area. If the capping members 50 were extended across the ventilatingarea the muntin bars 40 of tool resistant material could bev eliminated for some types of structures. The sumof the thicknesses of the portions of the flanges extending in a di.- rection normal to the glazing is considerably greater than the portion of the capping member 59 extending parallel to the'glazing and over- -lying the flanges. Thus, the portion of the capping membersextending in a direction normal to the glazing is much stronger than-the portion forming the bottom of the channel,

llachof.` the capping members 50 located above the vez-itilatingV area may be provided with downjwardly extending portions 5l, terminating in a hook or lip portionjarranged in spaced relaflange 55 is preferably provided with a longitudinalrecess 5l, supporting suitable sealing material Vclosing the juncture between the top of the closure frame 6U and the horizontal muntin bar extending across the top of the Ventilating area. Suitable holes 52 extending through the flanges of the muntin bars lll permit the pouring of fused metal to weld member 50 to the muntin bars. 'I'hese holes 52 may be positioned between the intersection of the transversely disposed muntin bars, so that the same weld unites three parts together without leaving exposed holes and without leaving exposed welds, that is, the vertical and the horizontal bars together with the capping member 5I are united by a single weld extending between the flanges of the vertical and the horizontal'bars and terminating in union with the capping member 5|. The putty holding the glazing conceals the Weld and protects it from the elements.

A clearance 59 is provided above the flange 55, so as to permit the insertion of the closure frame 50 by projecting the flange 55 into the clearance 59, moving the lower portion of the closure frame towards the main frame over the sill 64 to permit the closure to drop into position.r The clearance 59 may rst be filled with a suitable plastic to provide weather tightness and rigidity of the closure frame. The crevice between the downwardly projecting flange of the closure 60 and the sill 64 may be iilleld with suitable plastic o yieldable material 6I.

In the present instance the closure includes a movable member not shown, movably attached t0 the frame 50. A sill 54, interlocking the upwardly projecting flange of the muntin bar extending across the bottom of the Ventilating area, supports the bottom of the frame 60. The closure that is movably mounted may be pivoted at the bottom, at the top, at either side, in the center or otherwise mounted in position.

' Referring to the modications disclosed in Figs. 5 to 8 inclusive, the horizontal T-bars 10 have been provided with suitable openings for the reception of the vertical muntin bars 16. The flanges 80 are arranged in flush relation with respect to the flanges 82, as has been more fully described in my copending application Serial No. 82,847. The needle bars 1B, after being properly positioned as described in my copending application, are locked in position by key bars 84, preferably made of tool resistant material and square or rectangular in cross sectional ar-ea. The key bars 84 are preferably aligned and symmetrically disposed with respect to the webs and the anges of the muntin bars 16, so that the muntin bars 16 and the key bars 84 cooperate to form a pair of channels, one on either side of the webs of the muntin bars 16. In some structures the dividing `web 16 may be offset, so as to provide a shallow channel on one side and a deeper channel on the other side to facilitate glazing. By arranging the flanges and the key bar 84 in symmetrical relation, the offset relation of the web is inconspicuous after the window is completed.

For this type of construction it is desirable that the maximum width of the T-bars 16 be somewhat less than the width of the web of the horizontal bars T0. The key bars B4 are positioned -along the outer. edge of the webs of the T-bars 16, so as to have sufficient clearance for the insertion of the glazing. That being the case, the duo-functional detention and T-bars 84 may extend uninterruptedly across the Ventilating area and the glazed spaces.

In this modification it is not absolutely necessary in order to provide proper protection across the Ventilating area to have the muntin bars extend continuously across both the Ventilating area and thexed glazed spaces. The muntin bars` may terminate at the Ventilating area, thereby saving material and improving the vvisibility ofthis portion of the window. Suitable detention meansextending across the Ventilating areaY may be' used-to provide adequateprotection across th more vulnerable area of the window.

In thepmodication disclosed in Figs. 5 and 7, .transverse detentionbars 86, which mayphave notches `inthe sides thereof, extend across-.the Ventilating area and are welded-to the Vertical `T-`bars.84. The ends of the detention bars 86 are preferably welded to the muntin bars bounding the sides of the Ventilating area.

In some structures the horizontal bars 86, or forthat matter the vertical bars 84, may be eliminated at the fixed glazed spaces. `I f so, either the horizontal bars or the Vertical bars, or both, may beprovided with capping members 58 shown in Fig. 6, which capping members are similar tothose which have already been described in connection with the modification disclosed in Figs. 1 to 4 inclusive, and shown in; detail in Fig. 3. A .i

In Fig, 8 the capping membersalong the sides of the window extend in overlapping relation with respect to the flanges I8 of the muntin bars I4 bounding the sides of the window, so as to have `portions of the capping members embeddedin the `masonry of the wall. In some types of structures it is not necessary tohave the `capping members embedded in 'theV masonry. The capping members could Vthenfterminate in a manner similar to that shown in Fig. 7.

, `'Iihe unglazed; Ventilating area is preferably provided with a closure, only the frame S0 of .which has been shown, as any suitable movable closure may `be mounted upon the frame` 90to `close the Ventilating area.

The muntin bar extending across the top of the Ventilating area is provided with a metallic cappingmember 94 welded to the upwardly projecting flange through suitable fusing holes or pockets 96. These fusing holes or pockets 9B are `preferably located between the juncture of the `uanges of thevertical and the horizontal muntin Y bars, so that the weld holds three parts together, that is, the vertical and horizontal muntin bars `.and the capping member 94. Capping members l5l] and the key bars 84 may also beheld in posi'- holes.

lying`- an upwardly projecting flange 92 of the closureframe 9|).v

The lowerportion of the closure frame 90 is` `supported upon the sill 64 in a manner similar @to that alreadydescribed in connection with the preferred embodiment. Sufficient clearance has been provided so that the closure assembly may `be placedinposition byinserting the upwardly projecting ange 92 under the downwardly profjecting flange or the lip portion of member 94 and then thelower portion of the frame 9U moved `toward themain frame and slipped over. the top `of the sill 84 as it is dropped into position. Thus,

it is. seen that the closure for the Ventilating area `may be placed in position after the window has beenerected in the building, thereby reduc- `ing the cost of production, as it is possible to have the closure glazed and completely assemf bled on the jobA or at the factory before the closure and its frame is mounted in position.4

The` channel 51 in the closure 9D supports bars extending across the fixed putty or suitable sealingmaterial for sealingf the closure along three sidesV thereof. 'Ihe AVcrevice portion and arrangement of parts which gener l ally stated, consistin a device capable of carrying out the objects set forth, in the novel parts,

combination of parts and mode of operation, as
